Today and tonight...

active weather will continue today as a stronger, more organized
weather system will push through the mid mississippi valley region.

As this occurs, it will drop a cold front south toward the
arklamiss. Showers and storms will develop ahead of this front by
late this morning into early this afternoon and, with continued
ample moisture in place as characterized by pw values in excess of
two inches, this will bring the potential for additional heavy
rainfall. Given the wet antecedent conditions and potential for
efficient rainfall, additional flash flooding is possible today.

That being said, will continue the mention of this in the limited
risk graphic and hwo.

Cam guidance suggests that showers and storms will develop across
the eastern part of the forecast area late this morning. This
activity is not expected to be severe. However, as the front starts
to move into the region, there could be a few strong to severe
storms. The main limiting factor will be the lack of colder
temperatures aloft, which limits how steep the lapse rates will be.

Models continue to show rather meager lapse rates and vertical
totals. However, given the more organized nature of the system and
the fact there is some low to mid level shear present, this will
bring potential for a few severe storms, especially in the northwest
portion of the forecast area. In this region, we have kept the
marginal risk for severe storms with gusty winds being the primary
threat. It is possible that more of the delta could be under a
slight risk with later updates.

The upper trough will swing across the region Monday night, bringing
with it the aforementioned cold front. This will start to usher in a
drier airmass into the region, which will result in some cooler more
pleasant weather for a few days this week. Until then, highs today
should remain in the upper 80s and lower 90s and lows tonight will
once again be in the 70s. With dewpoints remaining in the 70s, it
will continue to feel muggy today. 28
Tuesday through the weekend...

by Tuesday morning, a cold front will be draped across arklamiss
with some showers and a few thunderstorms out ahead of it. Some
convective storms will fire ahead of and along the front as it
continues to trek southward through the region. A few strong
storms are possible in southern zones as the atmosphere will have
a little more time to destabilize ahead of the front. The front
should be clear of the arklamiss by Tuesday evening. Northerly
flow behind the front will help to bring a cooler, drier airmass
into the arklamiss.

Pleasant weather for mid late august standards will prevail
through the rest of the work week as the dry airmass remains over
the region. Highs on Wednesday and Thursday will remain a few
degrees below average with dewpoints remaining in the mid to
upper 60s. Early morning low temperatures will fall into the mid
to upper 60s across the region. Temperatures and moisture values
will begin to increase once again as we get closer to the weekend
and the broad high over us begins to shift east of the region.

06z TAF discussion:
mostlyVFR conditions are occurring this morning, with the
exception being at kmei which is already seeing low clouds and
resulting MVFR to ifr ceilings. Expect lower ceilings to affect
most other TAF sites around 08z. Conditions will slowly improve
through the morning following daybreak but scattered to numerous
tsra is expected later this morning into the afternoon as a cold
front pushes through the region. This will bring a reduction in
flight categories in any TAF site that sees tsra. 28

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
